Like the title says, how do you know how much wattage u need for ur computer?
Im in the process of building my first one. its a middle of the pack gaming computer. im going to spend about $550 to $600. nothing fancy. a buddy of mine told me to go 850W+. and i thought that would be overkill and i would only need about 700 MAX. he said the more the better, and it doesnt hurt to have a lot of wattage. but ive read that too much, or too little can be bad, and u need to find that middle ground.
So IS more better? is it better to be safe than sorry? or is there a guideline type thing u follow to calculate?
